随着人工智能、第五代移动通信技术(5G)和物联网等信息产业的快速发展以及算力需求的爆发式增长,数据中心和高性能计算对高速、低功耗和高密度互连技术的需求激增,2.5维(2.5D)、三维(3D)等先进光电封装技术受到大量关注并发展成为光电共封装(CPO)技术应用的关键解决方案。相比于传统有机和硅基转接板,玻璃基板凭借其优异的射频性能、面板级低成本制造、高稳定性和可靠性,成为下一代先进光电封装的重要技术路线。文章介绍了玻璃基光电集成封装技术中的关键技术,包括玻璃通孔(TGV)工艺、TGV转接板技术和光波导技术。同时,总结了CPO的应用现状,分析了国内外相关技术路线和进展,包括多种2.5D/3D封装的玻璃基CPO光交换和光引擎。此外,还指出可在玻璃基板上加工玻璃光波导器件,实现耦合、分束和复用等功能,进一步提高玻璃基光电集成的集成度和功能性。因此,玻璃基光电集成封装在CPO场景具有巨大技术优势和应用潜力,未来在光电混合计算和光传感等领域也有巨大的发展空间,是光电先进封装的重要技术路线。
With the rapid advancement of information technologies such as artificial intelligence
5th Generation Mobile Communication Technology (5G)
and the Internet of Things
along with the explosive growth in computational demands
data centers and high-performance computing systems are increasingly requiring high-speed
low-power
and high-density interconnection technologies. Advanced photonic packaging technologies such as 2.5 Dimensional (2.5D) and 3 Dimensional (3D) integration have garnered significant attention and evolved into key solutions for Co-Packaged Optics (CPO) applications. Compared to traditional organic and silicon-based interposers
glass interposer has emerged as a critical technological pathway for next-generation advanced photonic packaging
owing to their excellent radio-frequency performance
panel-level low-cost manufacturing
high stability
and reliability. This paper introduces the key technologies in the glass-based photonic integrated packaging technology
including the Through Glass Via (TGV) fabrication
the TGV Interposer technology
and the optical waveguide technology. At the same time
it summarizes the current application status of CPO
analyzes the relevant technical routes and progress both domestically and internationally
including various 2.5D/3D packaged glass-based CPO optical switches and optical engines. Moreover
it points out that glass optical waveguide devices can be processed on the glass substrate to achieve functions such as coupling
splitting
and multiplexing
thereby further improving the integration degree and functionality of glass-based photonic integration. Therefore
glass-based photonic integrated packaging offers significant technical advantages and application potential in CPO scenarios. It also holds substantial promise for future developments in areas such as photonic hybrid computing and optical sensing
establishing itself as a vital technological route in advanced photonic packaging.
